Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Be- und Entladen einer Stellplatte einer Gefriertrocknungsanlage gemäß dem Oberbegriff des Anspruches 1 und eine Gefriertrocknungsanlage gemäß dem Oberbegriff des Anspruches 2.The present invention relates to a device for loading and unloading an adjusting plate of a freeze-drying plant according to the preamble of claim 1 and a freeze-drying plant according to the preamble of claim 2.

Das in einer Gefriertrocknungsanlage zu trocknende Gefriergut wird in kleine Fläschchen, sogenannten Vials, abgefüllt und mit Hilfe dieser Vials transportiert. Auf diesen Vials sind Deckel vorgesehen, die nach Beendigung des Gefriertrocknungsverfahrens geschlossen werdenAus der EP 1 619 459 A1 ist es bekannt, die mit dem Gefriertrocknungsgut befüllten Vials auf einen Übergabetisch zu bringen und von dort mit einer Schiebevorrichtung auf eine Stellplatte in das Innere der Gefriertrocknungsanlage zu transportieren. Diese Schiebevorrichtung kann beispielsweise ein einfacher Schieber sein. Damit bei dem Transport die Vials nicht versehentlich vom Übergabetisch herunterfallen, besitzt dieser an seiner rechten und linken Außenseite einen Seitenbegrenzer. Analoges gilt für die Stellplatte innerhalb der Gefriertrocknungsanlage, denn auch an dieser Stellplatte sind rechts und links Seitenbegrenzer vorgesehen, damit die Vials nicht versehentlich herunterfallen.The frozen food to be dried in a freeze-drying plant is filled into small vials, and transported with the aid of these vials. Lids are provided on these vials which will be closed after completion of the lyophilization process EP 1 619 459 A1 It is known to bring the filled with the Gefriertrocknungsgut vials on a transfer table and to transport from there with a pusher on an adjusting plate in the interior of the freeze-drying plant. This sliding device may for example be a simple slider. So that during transport, the vials do not accidentally fall off the transfer table, this has on its right and left outside a Seitenbegrenzer. The same applies to the positioning plate inside the freeze-drying system, because side and side limiters are also provided on this positioning plate so that the vials do not accidentally fall off.

Beim Hineinschieben der Vials vom Übergabetisch auf die Stellplatte berühren einige der Vials den Seitenbegrenzer, wobei es zu erhöhter Reibung kommt. Dies hat zur Folge, dass sich die äußeren Vials langsamer als die inneren Vials bewegen mit der Folge, dass hierbei die Anordnung der Vials untereinander verändert wird. Im Extremfall kann hierdurch sogar das eine oder andere Fläschchen umfallen, was zu erhöhtem Ausschuss führt.When pushing in the vials from the transfer table to the shelf, some of the vials touch the side limiter, resulting in increased friction. As a result, the outer vials move more slowly than the inner vials with the result that the arrangement of the vials is changed among themselves. In extreme cases, even one or the other vials fall over, which leads to increased rejection.

Aus der DE 100 15 566 A1 ist eine Fördereinrichtung zum Fördern von Flaschen oder dergleichen bekannt, bei dem die jeweiligen Flaschen über einen längeren Weg auf einem Förderband transportiert werden, an dem rechts und links Seitenbegrenzer vorgesehen sind, um ein Herunterfallen der Flaschen vom Förderband zu verhindern. Diese Seitenbegrenzer umfassen vertikal zum Förderband angeordnete bewegliche Anlagemittel, an denen die Flaschen zur Anlage kommen. Diese Anlagemittel sind in der Regel um entsprechende Umlaufrollen angeordnete Bänder. Stoßen nun die auf dem Förderband transportierten Flaschen an den Bändern an, so bewegen sich die Bänder zusammen mit den Flaschen in die entsprechende Richtung. Hierdurch wird die Relativgeschwindigkeit zwischen den Flaschen und den Bändern verringert. Die jeweiligen Bänder erstrecken sich über eine gewisse Länge und sind kraftschlüssig an den Umlenkrollen gehalten. In der Praxis hat sich herausgestellt, dass beim Berühren der Bänder durch die Flaschen eine vergleichsweise große Kraft aufgewendet werden muss, um das Band in Bewegung zu setzen. Dies liegt zum einen daran, dass das Band eine gewisse Länge aufweist und dass das Band unter Spannung steht.From the DE 100 15 566 A1 a conveyor for conveying bottles or the like is known, in which the respective bottles are transported over a longer distance on a conveyor belt, on the right and left side limiters are provided to prevent falling of the bottles from the conveyor belt. These Seitenbegrenzer comprise vertically to the conveyor belt arranged movable attachment means, where the bottles come to rest. These attachment means are usually arranged around corresponding circulation rollers belts. Now push The bottles transported on the conveyor belt on the belts, so move the belts together with the bottles in the appropriate direction. This reduces the relative speed between the bottles and the belts. The respective bands extend over a certain length and are frictionally held on the deflection rollers. In practice it has been found that a relatively large force has to be applied when touching the bands through the bottles in order to set the band in motion. This is partly because the band has a certain length and that the band is under tension.

Beim Einsatz einer derartigen Technik bei einer Vorrichtung zum Be- und Entladen einer Stellplatte einer Gefriertrocknungsanlage mit einer Anzahl von Vials würde aber der verbleibende Reibungswiderstand bzw. der zum Bewegen des Bandes erforderliche Kraftaufwand die einzelnen Vials abbremsen und somit die Ordnung der Vials auf dem Übergabetisch in Unordnung bringen.When using such a technique in a device for loading and unloading a shelf of a freeze dryer with a number of vials but the remaining frictional resistance or the force required to move the tape would slow down the individual vials and thus the order of the vials on the transfer table in Bring disorder.

Davon ausgehend liegt der vorliegenden Erfindung die Aufgabe zu Grunde, eine Gefriertrocknungsanlage und eine Vorrichtung der eingangs genannten Art zu schaffen, so dass die Vials unter Beibehaltung ihrer Reihenfolge und Ordnung in die Gefriertrocknungsanlage hinein und wieder herausgeführt werden können.Based on this, the object of the present invention is to create a freeze-drying plant and a device of the type mentioned at the outset, so that the vials can be led into and out of the freeze drying plant while maintaining their order and order.

Als technische Lösung dieser Aufgabe wird erfindungsgemäß eine Gefriertrocknungsanlage mit den Merkmalen des Anspruches 2 und eine Vorrichtung mit den Merkmalen des Anspruches 1 vorgeschlagen. Vorteilhafte Weiterbildungen dieser Vorrichtung sind den Unteransprüchen zu entnehmen.As a technical solution to this problem, a freeze-drying plant according to the invention with the features of claim 2 and a device having the features of claim 1 is proposed. Advantageous developments of this device can be found in the dependent claims.

Eine nach dieser technischen Lehre ausgebildete Vorrichtung und eine nach dieser technischen Lehre ausgebildete Gefriertrocknungsanlage hat den Vorteil, dass die beweglichen Hohlzylinder des Seitenbegrenzers den angreifenden Vials keinen oder nur einen geringen Widerstand entgegensetzen, so dass die Reibung zwischen dem eigentlichen Seitenbegrenzer und den Vials hierdurch auf ein Minimum reduziert wird. Hierdurch können die Vials an dem Seitenbegrenzer entlang gleiten, ohne behindert zu werden. Folg-lich können sich die am Rand befindlichen Vials, also diejenigen Vials, die am Seitenbegrenzer anstoßen, genauso reibungsarm und schnell fortbewegen, wie alle anderen Vials, was zur Folge hat, dass die Vials untereinander ihre Ordnung und Reihenfolge behalten. Dies wiederum hat den großen Vorteil, dass bei einer Überprüfung der Vials nach dem abgeschlossenen Gefriertrocknungsvorgang der Standort der nicht ausreichend gefriergetrockneten Vials einfach bestimmt werden kann, so dass der Ausschuss reduziert werden kann und mögliche Fehlerquellen erkannt werden.A trained according to this technical teaching apparatus and trained according to this technical teaching freeze dryer has the advantage that the movable hollow cylinder of the Seitenbegrenzers oppose the attacking vials little or no resistance, so that the friction between the actual Seitenbegrenzer and the vials thereby on a Minimum is reduced. This allows the vials to slide along the side limiter without being obstructed. As a result, the vials on the edge, ie those vials that abut the side limiter, can move as smoothly and quickly as any other vial, with the result that the vials keep their order and order among themselves. This, in turn, has the great advantage that reviewing the vials after completion of the freeze-drying process will easily determine the location of the insufficiently freeze-dried vials so that rejects can be reduced and potential sources of error identified.

Noch ein weiterer Vorteil der bewegbaren Hohlzylinder des Seitenbegrenzers besteht darin, dass die Vials beim Auftreffen auf die Seitenbegrenzer nunmehr keinen ernsthaften Widerstand mehr erfahren und somit auch nicht umfallen können, was zu einer Reduzierung des Ausschusses führt.Yet another advantage of the movable hollow cylinder of the side limiter is that the vials now encounter no serious resistance when hitting the side delimiters and thus can not fall over, which leads to a reduction of the reject.

Bei den an der Stellplatte einer Gefriertrocknungsanlage angebrachten Seitenbegrenzern hat es sich als vorteilhaft erwiesen, diese rechts und/oder links neben der Stellfläche anzubringen. Hierdurch ist es möglich, die übereinander angeordneten Stellplatten in an sich bekannter Art und Weise platzsparend aufeinander zu legen, umso die gewünschte Stellplatte an die Öffnung der Gefriertrocknungsanlage zum Be- und Entladen heranzuführen.When mounted on the shelf of a freeze-drying plant Seitenbegrenzern, it has proven to be advantageous to attach these right and / or left of the footprint. This makes it possible to place the superimposed control panels in a manner known per se to save space, so as to introduce the desired control panel to the opening of the freeze-drying plant for loading and unloading.

In einer bevorzugten Ausführungsform sind die Hohlzylinder so eng nebeneinander angeordnet, dass kein Vial dazwischen hindurchfallen kann. Insbesondere wenn diese Hohlzylinder auf einem innenliegenden Stift gehalten sind, können diese um ihre Hochachse reibungsarm rotieren. Dabei werden die Hohlzylinder beim Auftreffen eines Vials in Rotation versetzt, so dass dem Vial ein entsprechend geringer Widerstand entgegengebracht wird. Auch hierdurch wird erreicht, dass die Relativgeschwindigkeit zwischen dem Seitenbegrenzer und dem Vial auf ein Minimum reduziert ist.In a preferred embodiment, the hollow cylinders are arranged so close together that no vial can fall between them. In particular, when these hollow cylinders are held on an inner pin, they can rotate around their vertical axis friction. The hollow cylinders are set upon rotation of a vial in rotation, so that the vial is given a correspondingly low resistance. This also ensures that the relative speed between the side limiter and the vial is reduced to a minimum.

In einer bevorzugten Weiterbildung umfasst der Seitenbegrenzer zwei übereinander angeordnete Reihen von Hohlzylindern, welche bevorzugterweise versetzt angeordnet sind. Dies hat den Vorteil, dass die den Vials zugewandte Fläche des Seitenbegrenzers gleichmäßiger wird, da durch die versetzt angeordneten Hohlzylinder die Unebenheiten reduziert sind. Hierdurch werden die an den Vials auftretenden Kräfte noch weiter reduziert, so dass die an den Seitenbegrenzern anstoßenden Vials mit annähernd derselben Geschwindigkeit bewegt werden können, wie alle anderen Vials, was zur Beibehaltung der Ordnung und der Reihenfolge der Vials führt.In a preferred development, the side limiter comprises two rows of hollow cylinders arranged one above the other, which are preferably arranged offset. This has the advantage that the surface of the Seitenbegrenzers facing the vials is more uniform, since the irregularities are reduced by the staggered hollow cylinder. This further reduces the forces on the vials so that the vials abutting the side limiters can be moved at approximately the same speed as all other vials, maintaining the order and order of the vials.

Ebenso können die vorstehend genannten und die noch weiter ausgeführten Merkmale erfindungsgemäß jeweils einzeln oder in beliebigen Kombinationen miteinander verwendet werden.

In Fig. 1 bis 3a ist eine erfindungsgemäße Vorrichtung 100 zum Be- und Entladen einer Stellplatte einer Gefriertrocknungsanlage, sowie eine Ausführungsform einer dazugehörigen Gefriertrocknungsanlage 102 dargestellt. Beide Anlagen sind nur schematisch dargestellt, um die Anschaulichkeit zu erhöhen. Die Gefriertrocknungsanlage 102 umfasst einige im Inneren angeordnete Stellplatten 104, die vertikal verschiebbar gehalten sind. Die vor der Gefriertrocknungsanlage 102 angeordnete Vorrichtung zum Be- und Entladen einer Stellplatte umfasst einen Übergabetisch 106, eine hier nicht näher dargestellte Schiebevorrichtung zum Verschieben der Vials und eine Transportvorrichtung 108, mittels der die Vials dem Übergabetisch 106 zu- bzw. abgeführt werden.In Fig. 1 to 3a a device 100 according to the invention for loading and unloading an adjusting plate of a freeze-drying plant, and an embodiment of an associated freeze-drying plant 102 is shown. Both systems are only shown schematically to increase the clarity. The freeze dryer 102 includes a few internally disposed actuators 104 that are vertically slidable. The apparatus for loading and unloading a positioning plate arranged in front of the freeze-drying installation 102 comprises a transfer table 106, a sliding device, not shown here, for moving the vials and a transport device 108, by means of which the vials are fed to and removed from the transfer table 106.

Am rechten und linken Rand des Übergabetisches 106 ist je ein Seitenbegrenzer 110 vorgesehen, der ein versehentliches Herunterfallen der Vials vom Übergabetisch 106 verhindert. Ein im Wesentlichen baugleicher Seitenbegrenzer 112 ist am rechten und linken Rand der Stellplatte 104 angebracht. Wie insbesondere Fig. 3a zu entnehmen ist, ist der Seitenbegrenzer 112 vollständig neben der Stellplatte 104 angebracht, damit beim Zusammenschieben der vertikal verschiebbaren Stellplatten 104 die nächste darüber liegende Stellplatte ebenfalls zwischen die Seitenbegrenzer 112 gelangen kann, um die einzelnen Stellplatten 104 möglichst dicht beieinander zu stapeln.On the right and left edges of the transfer table 106, a side limiter 110 is provided, which prevents accidental dropping of the vials prevented from the transfer table 106. A substantially identical side limiter 112 is mounted on the right and left edges of the actuator plate 104. In particular Fig. 3a can be seen, the Seitenbegrenzer 112 is mounted completely adjacent to the adjusting plate 104, 104 so that when pushing together the vertically displaceable positioning plates 104, the next overlying control plate can also get between the Seitenbegrenzer 112 to stack the individual panels 104 as close to each other.

Der Seitenbegrenzer 110 besitzt eine untere Reihe von Hohlzylindern 114 und eine obere Reihe von Hohlzylindern 116, die so angeordnet sind, dass der jeweils äußerste Punkt ihrer Zylinderoberfläche quasi die Seite des Seitenbegrenzers 110, 112 bildet. Alle Hohlzylinder 114, 116 sind um ihre Hochachse rotierend angeordnet und auf einem entsprechenden Stift 118 reibungsarm gehalten, so dass ein auf dem Hohlzylinder 114, 116 auftreffendes Vial diesen in Rotation versetzt, ohne dabei einen großen Widerstand in Transportrichtung zu erfahren.The side limiter 110 has a lower row of hollow cylinders 114 and an upper row of hollow cylinders 116, which are arranged such that the outermost point of their cylinder surface forms the side of the side limiter 110, 112, as it were. All of the hollow cylinders 114, 116 are arranged to rotate about their vertical axis and are held with low friction on a corresponding pin 118, so that a vial striking the hollow cylinder 114, 116 causes it to rotate without experiencing any great resistance in the transport direction.

Die Hohlzylinder 114 der unteren Reihe sind gegenüber den Hohlzylindern 116 der oberen Reihe versetzt angeordnet, wie insbesondere den Fig. 1a und 2a zu entnehmen ist. Hierdurch wird eine relativ hohe Seitenwand des Seitenbegrenzers 110, 112 geschaffen, die ein reibungsarmes Entlanggleiten des Vials entlang des Seitenbegrenzers 110, 112 bewirkt. Durch die rotierbar gelagerten Hohlzylinder 114, 116 kann auch die Relativgeschwindigkeit zwischen dem zu transportierenden Vial mit dem Seitenbegrenzer 110, 112 auf ein Minimum reduziert werden, um einen möglichst gleichmäßigen Transport aller Vials zu erreichen.The hollow cylinders 114 of the lower row are offset relative to the hollow cylinders 116 of the upper row, in particular the Fig. 1a and 2a can be seen. As a result, a relatively high side wall of the side limiter 110, 112 is created, which causes a low-friction sliding of the vial along the side limiter 110, 112. By the rotatably mounted hollow cylinder 114, 116, the relative speed between the transported vial with the Seitenbegrenzer 110, 112 can be reduced to a minimum in order to achieve the most uniform transport of all vials.
